A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water and is connected to a cumuliform cloud. In the common form, it is a nonsupercell tornado over water, and brings the water upward. Also, it is weaker than most of its land counterparts

An intense, and almost certainly exceptional, depression crossed the coast of South Devon soon after midnight, moving quickly, and deepening rapidly, with a track across the Midlands and out towards the Humber Estuary. Some very severe conditions due to storm force winds were generated around the southern and eastern flank of the low, with gust well in excess of 70 knots, reaching a peak in the period 0300GMT to 0700GMT, with gusts to 90 knots reported along the south coast. The very stormy conditions were accompanied by some heavy rain, this rain pushing into Scotland and parts of Northern Ireland after dawn.Clearer weather, on westerly winds, swept across southern Britain, pushing the worst of the stormy winds away into the North sea. During the afternoon the country settled down to a blustery westerly with some heavy and thundery showers developing in clusters, running especially into western and southern coastal regions and parts of southeast England. Across Scotland and northern England the skies remained cloudy, with outbreaks of mostly light rain, but troughs enhanced the showers in the northwest later in the evening with heavy rain.It was a rather cold day in most places, although the temperatures were near normal in the southeast.
